MAX5079 Datasheet Oring MOSFET Controller

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-3584; Rev 0; 2/05 www.DataSheet4U.com ORing MOSFET Controller with Ultra-Fast 200ns.

General Description

The MAX5079 ORing MOSFET controller replaces ORing diodes in high-reliability redundant, parallel-connected power supplies.

Despite their low forward-voltage drop, ORing Schottky diodes cause excessive power dissipation at high currents.

The MAX5079 allows for the use of low-on-resistance n-channel power MOSFETs to replace the Schottky diodes.

Key Features

  • include an OVP flag to facilitate shutdown of a failed power supply due to an overvoltage condition, and a PGOOD signal that indicates if VIN is either below the undervoltage lockout or VBUS is in an overvoltage condition. The MAX5079 operates over the -40°C to +85°C temperature range and is available in a space-saving 14-pin TSSOP package.
  • 2.75V to 13.2V Input ORing Voltage.
  • 1V to 13.2V Input ORing Voltage with 2.75V Aux Voltage Present.
  • 2A MOSFET Gate Pulldown Curre.
